Fractional CTO

A fractional CTO who ships code, not slides

Senior technical leadership for non-technical founders — someone who owns the roadmap and the architecture, and still writes the code that ships every week.

Book a call

Retainer from 1 to 5 days a week. Async-first, US and EU time zones.

Who it’s for

01

Non-technical founders

You own the vision and the customers. You need someone you trust to own the technical side and explain every decision in plain language.

02

Pre-seed to Series A

Too early or too lean for a full-time CTO, too far along to keep guessing. You need senior judgement now, at a fraction of a full-time cost.

03

MVPs that outgrew their first build

The first version proved the market, but it’s slowing you down: fragile releases, growing costs, a codebase nobody wants to touch.

What you get

  • Product & technical roadmap

    What to build next, in what order, and what to deliberately not build — tied to your fundraising and revenue milestones.

  • Architecture

    A stack and data model chosen for where you’re going, documented so the next engineer can pick it up.

  • Hands-on development

    Not just advice: features, fixes and refactors shipped by the same person who designed them.

  • Hiring help

    Job specs, technical interviews and onboarding when it’s time to build your own team.

  • Investor & due diligence prep

    Technical sections of your deck, data room answers, and a codebase that holds up to a tech due diligence.

How it works

  1. 01

    Monthly retainer

    A fixed monthly fee for a set number of days per week — 1 to 5 — adjustable as your stage changes.

  2. 02

    Async-first, with daily updates

    A written update every working day: what shipped, what’s next, what needs your decision. Calls when they add something.

  3. 03

    US and EU time zones

    Based in Paris and working with founders on both sides of the Atlantic, with overlap hours for US teams.

Pricing from $3,500/month

Monthly retainer, scaled to the number of days per week. No long-term lock-in.

Questions

What is a fractional CTO?

A senior technical leader who works with your company part-time — usually 1 to 5 days a week — instead of as a full-time employee. You get the strategic side (roadmap, architecture, hiring) and, with Lowcodr, the hands-on development too.

How is this different from hiring a dev agency?

An agency delivers a scope. A fractional CTO owns the outcome: deciding what to build, challenging the plan, and keeping the codebase healthy over months — while still shipping code.

How much does a fractional CTO cost?

From $3,500 a month, depending on the number of days per week. A senior full-time CTO typically costs several times that, plus equity and months of recruiting.

Can you work with my existing developers?

Yes. We can lead and review the work of an in-house or freelance team, set up the engineering practices, and fill the gaps ourselves.

What happens when we hire a full-time CTO?

That’s a good outcome. We help recruit them, hand over the architecture and documentation, and step back or stay on as support — your call.
